Hello simpleman,
from what you wrote it sounds like you still would like to have a relationship with her-
One idea is that this could be a relationship of a different more a friendship/coaching kind. There are significant draw-backs and risks:
It is not easy to change the character of a relationship and it takes two mature people to do so well. A pwBPD almost by definition lacks maturity. Also there is a risk that you take a position of a T without being one. To simply coach her you are lacking the necessary distance. Last but not least by continuing to be semi close you prevent both sides to detach and heal.
It is generally considered a bad idea to tell the pwBPD that they are dealing with BPD. From the place you are at the moment the message may well do more damage as it has potential to do good.
There is no way I could recycle at this point. I am still too damaged and am seeing a T 2Xweek to work on that. And I need codependency work. But I would be open to her working on herself and me working on myself apart and then see what happens. If we did that I would want to stipulate that we don't date other people. Maybe that is not fair but that is a big one to me.
And for that very reason helping her will be detrimental to you. You need to put yourself first at this time. Once you are in a place where you are comfortable with putting yourself first you may have other options with her or other partners.
So am I crazy? Could something like that possibly work?
No, but breaking up a BPD relationship is painful and some level of depression with twisted thinking is common (see LESSONS on on the Leaving board). Unlikely it will work, likely it leads to prolonged pain and drama extended to the workplace. But if want to be sure ask your T.
The way I see it there are two options:
A) Recycling. Then you are in a relationship and can work within the framework of the LESSONS of the Staying board.
B) Working on detaching (see LESSONS on Leaving board) and giving priority to yourself. As NC is not feasible for you then an alternative is to maintain LC (Low Contact). A good idea might be to spend time to practice validating communication (see workshop section) with many people. Validating her is reasonably safe as it tends to have positive impact on relationships without increasing much unhealthy attachment. Still any communication with her should be done in the context of LC and not as half baked recycling attempt.
There is beauty in keeping things simple, simpleman
